PowerColor RX Vega 64 Undervolt and Overclock Benchmarks

PowerColor RX Vega 64 Undervolt and Overclock

Hello everyone. Will here and today, I am bringing you some benchmark numbers from the PowerColor Red Devil RX Vega 64 graphics card and how well or not so well it overclocks using AMD’s Global Wattman overclocking software. I was curious yesterday about overclocking this card and decided to try out if undervolting the card was actually as beneficial as some have said. So, here we are. How did the card perform at various settings? Well, let us take a look.

Test System

The system used for testing was the AMD Ryzen 5 2600 overclocked to 4.1GHz on the MSI B350 Mortar motherboard. On board, there is 16GB of G.Skillz TridentZ RAM clocked at 3400MHz in 2x8GB configuration, dual channel. Cooling the CPU is the Noctua NH-D15. Of course, the graphics card used in this testing is the PowerColor Red Devil RX Vega 64 graphics card and all of the components are powered by the Corsair CX650M housed inside of the Fractal Design Meshify C Mini Dark TG case.

Test Methods

The PowerColor Red Devil RX Vega 64 graphics card comes with 8GB of HBM2 memory and has 4096 stream processors. The card comes out of the box with a base clock of 1417MHz and a boost clock of 1607MHz.

For testing, I used AMD’s Global Wattman overclocking software, leaving the BIOS on the Red Devil set on the OC setting. I trialed 4 different settings in Global Wattman: (1) Power Save, (2) Balanced, (3) Turbo, and (4) Custom which had a 5% frequency overclock on the core and a 1075MHz overclock on the HBM2 memory. Power state 6 was set at 1075mV and power state 7 was set at 1100Mv while the memory voltage power state 3 was set at 1000mV. I had the power limit set to an additional 50% and left fans and temperature controls on automatic. I tested just one game and that was Grand Theft Auto V with settings maxed out at 1080p (see photos below for complete settings used). I ran the in-game benchmark utility for 5 runs per each mode tested and compiled an overall average of 1% Lows and average FPS; also included is the single lowest FPS mark recorded.

Testing

First, I tested the Global Wattman “Power Save” setting. During the benchmark runs, the lowest recorded FPS was 39 FPS along with an overall average of 53 FPS and a 1% low of 44 FPS.

Next, the “Balanced” mode was tested. During the benchmark runs, the lowest recorded FPS was 38 FPS along with an overall average of 56 FPS with a 1% low of 43 FPS.

In the Global Wattman “Turbo” mode benchmark runs, the lowest recorded FPS was 36 FPS with an overall average of 58 FPS and a 1% low of 44 FPS. Finally, on the custom mode, the lowest recorded FPS was 44 FPS with an overall average of 61 FPS and a 1% low of 52 FPS.

Conclusion

So, there you have it. As you can see, a slight undervolt on core and memory with a slight, stable core overclock and rather large overclock on the memory actually did improve performance. The resulting 15.79% improvement in the single lowest FPS, the 20% improvement in the 1% low, and the 9% improvement in average FPS is fairly significant. These improvements are obviously based on the default “balanced” mode in Global Wattman versus a quick and fairly small overclock and undervolt which leaves plenty of room for further adjustments which would most likely result in even better performance.

Final Thoughts

Now, my final thoughts. Should you undervolt and overclock your core and memory? Well, given these results, I’d say absolutely. You will save yourself a few cents every month on electricity though not really a significant amount but also, you will decrease the noise in the room caused by the fans spinning up extremely fast to keep an already hot core/memory cool enough to operate effectively. These numbers were significant enough for me to say that yes, if you have any Vega card, you should definitely do some adjusting using the AMD Global Wattman software and undervolt your card while overclocking it. Thanks for stopping by. Leave a comment below and let me know what you think and don’t forget to vote in the poll. Be sure to share this article with your friends. Thanks again and have a great day!
